T0 @ZZ whom it may concern:

Be it known that I, ARTHUR R. SELDEN, a citizen of the United States, and a resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to a new and improved wrench for use with the taps or bungs for barrels or casks ot the type shown in United States Patent No. 600,501, dated March 8, 1898; and it consists of the wrench mechanism hereinafter described.

In the drawings, Figure l is a vertical seotion of a tap and wrench embodying this invention. Fig. 2 is an elevation of the Wrench on the `side of the handle thereof. Fig. 3 is a bottom plan view of the wrench. Figs. 4, 5, and 6 are cross-sections on the lines 4 4, 5 5, and 6 6 of Fig. 1, respectively. Fig. 7 is a bottom view of the tap or bung shown in Fig. 1, and Fig. 8 is an enlarged perspective View of the tightening-nut on the valve-stem.

In the drawings, b is the tap or bung, provided on its exterior with screw-threads b' for engaging the side walls of a perforation in the barrel or package, as usual. Inside the outer end of the tap or bung are the usual cam-slots b, adapted to engage cams upon a faucet that is inserted in said tap or bung in a well-known manner. In the outer end of the bung are notches o0 to permit the passage of the cams upon the faucet in a manner also well known. Below the cam-slots b4 is a circular valve-seat b3, against which a angeon the faucet (with an intermediate washer, if desired) engages in a manner well known. The valve-seat b3 is centrally perforated, and there is an enlarged chamber o0' within the body of the tap or bung.

The tap or bung has a bottom web b, provided with a suitable number of apertures or ports o7. In the present case there are shown two of these apertures or ports. The valvedisk cl2, provided with a packing d20, if desired, lits against the innerend of the tap or bung and against the face formed by the web b5 and has wings a, (see Fig. 7,) that are adapted to cover the ports or apertures b7 in certain positions of the valve-disk and to uncover said ports or apertures in other positions thereof.

The valve-disk dzhas a valve-stein CZ, that eX- tends through a central aperture in the web h6 upward and into the chamber o0' inside the bung. The central aperture through the Web h6 may have an upward cylindrical extension b9. The valve-stem is flattened on one side, as shown at d, Fig. 6, and on the stem is a `Washerdf, having a face fitting the face d6, as

shown in Fig. G, in order that the washer may not turn upon said stem. The said washer has wings d10, which act as guards to prevent wires being inserted from the outer end of the tap or bung through the apertures or ports 127. The Washer is so set upon the stern d that when the valve is closed the valve-disk d2 closes the apertures 197 and the Wings alo cover said apertures. On the valve-'stem and above the Washer is the nut dlg, provided With a series of notches d in its outer edge. This nut fits upon a screw-threaded portion of the stem and is adapted to force the washer against the web o6 or its flange b9, and thus by tightening the nut to draw the valve-disk d2 tightly against the inner face of the web o6. The upper end of the valve-stem d is preferably triangular, as shown in Fig. 5. lar end is adapted to lit into the end of the usual faucet in order that when the faucet is turned the ports b7 are opened and duid may pass out from the barrel or package. 1

The form of wrench in Fig. l5 of the drawings forming part of United States Patent No. 600,501, dated March 28, 1898, may be so used as to loosen the nut C112 (shown in Fig. 12 of said patent) without maintaining the proper angular position of the valve-disk d2 with reference to the ports a3 in the body of the tap b. Itis important to maintain the position of the valve-disk with reference to said ports in order that when the barrel is de livered to the customer it may be properly adjusted, so that when the faucet is inserted into the tap the proper engagement of the cams f4 may take place with the cams b4 in the tap, and also that the valve may be so set by means of the wrench that the valvedisk completely covers the ports. Any failure of adjustment of this character may permit leaking from the. barrel, particularly when there is gas-pressure inside it.

In order to avoid the objections above men- This triangu- IOI) tioned and to provide a wrench by which the nut (i12 may be tightened upon the valve-stem d in order to cause proper compression of the valve-disk d2 against the innerend of the tap and at the saine time to cause a proper setting of the valve-disk, the invention herein described has been produced.

The wrench to which this invention relates is adapted for use with a bunghaving a valve, a valve-stern inside the bung, and a tightening-nut on said stem and is composed, broadly, of a wrench for turning said nut, a spindle rotatable inside said wrench and adapted to engage said valve-stem to hold it, and means connected with said spindle for engaging the bung to hold the spindle stationary while the wrench is turned. The mechanism comprising the present embodiment of this invention has a central spindle g, having a socket g' in its lower end adapted to fit upon the triangular end of the valvestem d. This central spindle has a shoulder g2, larger than the main portion of the stem. Around the central stem is a sleeve h, integral with or fastened to ahandle h', extending outward from the sleeve. The sleeve fits upon i the spindle g and is provided with a shoulder corresponding to the shoulder g2, so that the sleeve cannot slip oi the spindle, but may turn thereon. The end of the sleeve is adapted to extend over the end of the spindle and is provided with projections h2, which are so proportioned and arranged as to t the notches (Z13 in the nut d. Upon the outer end of the spindle g is a cap j, that is securely fastened to said spindle in any suitable manner, such as by the pin j. The cap has downwardly-extending lugs jg, that are adapted to iit into the notches or recesses b of the tap or bung Z9. The handle h extends out through an opening js in the side of the cap j, and the cap has an interior recess, so that the sleeve h may slide longitudinally upon the spindle g, but without being removable therefrom.

The operation of the wrench is as follows: The wrench is inserted into the tap, the triangular socket g of the spindle g fitting upon the triangular end of the valve-stem d and the lugs 7'2 of the cap j tting in the notches bo within the tap or bung. It will now be seen that the valve-stem d cannot be turned so long as these parts are in place, while the sleeve or wrench proper, h, may be turned by means of the handle h. On lowering the sleeve h the lugs h2 engage the notches @Z13 in the nut 0112, and on turning the handle h to one side or the other the nut may be turned, tightening or loosening it, as the case may be. After moving the nut in one direction the handle h is raised, thus lifting the lugs h2 out of the notches in the nut dm, and then the sleeve may be turned back to a position for a new engagement with said nut, so that the nut may befurthertightened orfurtherloosened. The proportions of the parts of this Wrench are such, as shown in the drawings, that it cannot be employed to turn the nut unless the valve-stem d is held firmly against revolution by means of engagement of the socket in the spindle g with the Valve-stem and the engagement of the lugs jg with the bung or tap, and the nut d12 cannotbe turned unless the valvestem is so held, and the lugs 'i2 are of such length that the spindle cannot engage the valve-stem unless the lugsj2 are in the notches bo, thereby necessitatingthe non-rotatability of the valve stein whenever the sleeve or wrench his inserted into the bung far enough to engage the nut d. Further, the position of the lugs l7'2 with reference to the socket g in the spindle necessitates the invariable set ting of the valve-disk d2 in accurate relation to the ports 197. Of course the ends of the stem need not be triangular, but maybe of any suitable form other than cylindrical.
